Force measurement system

About

The FMS-EM is a compact force readout tool for the MM3A-EM micromanipulator. It enhances your system by allowing you to perform force measurements and nanoindentation.

Smallest outer dimensions are possible by means of a force readout system that requires no laser. Force feedback on the display of the controller is coupled with a loudspeaker to enable you to intuitively characterize materials and micromechanical structures by their resonance frequencies. Sharp silicon tips allow nanoindentation in a wide variety of materials.

The latest version of the system offers a complete force measurement solution including software for data acquisition, visualisation and export. The controller offers easy operation, measurement calibration at the touch of a button and a USB interface. The novel software features a calibration wizard for the Force Measurement Tips and is capable of recording force-time curves.

The plug-in holder and force sensors can be quickly and easily retrofitted to your existing MM3A-EM micromanipulator.
